Background technology
The basis of up link (UL) and down link (DL) scheduling is dynamic dispatching.In Long Term Evolution (LTE) wireless communication system, schedule information sends to wireless transmitter/receiver unit (WTRU) via physical downlink control channel (PDCCH) during Transmission Time Interval (TTI).Radio access network (RAN) working group (being RAN2) is with the semi-continuous scheduling that has been intended among the LTE to support to be used for DL and UL.For in TTI by the WTRU of semi-continuous scheduling, need not send DL/UL for initial data transfer and authorize.Unique exception is to want not take into account (override) persistent resources and divide timing when evolved Node B (eNB), but is infrequent according to this situation of definition.Otherwise will lose unique target that the DL/UL persistent resources is distributed.As the optimization of the voice (VoIP) of agreement Network Based, continuous dispatching is used to DL and UL, and the resource that wherein is used for initial transmission is to continue to distribute, and the resource that is used for mixed automatic repeat request (HARQ) transmission is a dynamic assignment.
The persistent resources scheduling is configured and controls (for example opening and closing) by radio resource control (RRC) signaling.For example, can based on the periodicity of resource allocation to persistent resources scheduling control.Use the RRC signaling to be provided for the HARQ process of continuous dispatching.
The definite timing, resource and the transmission format parameters that are used for continuing the DL distribution are distributed on layer 1 (L1)/layer 2 (L2) control channel as normal DL and are sent out.For example, HARQ process identification (PID) (ID) can be used to indicate described distribution to be stored.If described lasting DL distributes lose, then enhancement mode Node B (eNB) resends described distribution, and wherein said loss situation does not occur when having affirmative acknowledgement or negative response (NACK).
For the VoIP business, all very important in the release of the semi-continuous resource of DL and UL.Explicit resource release and implicit expression resource be discussed had before this been discharged, but still be necessary further decision is done in the enforcement of these characteristics.
In addition, also need to be used to use explicit and implicit method to support the potential new signaling of persistent resources, be used for explicit or process that the implicit expression persistent resources is distributed, failure scenarios when the persistent resources release signaling is lost or be destroyed is handled, be used to activate the new signaling of persistent resources and be used to reshuffle the new signaling that persistent resources distributes illustrates one by one.

As described below, term " wireless transmitter/receiver unit (WTRU) " includes but are not limited to the subscriber equipment that can operate of subscriber equipment (UE), mobile radio station, fixing or moving user unit, beep-pager, cell phone, PDA(Personal Digital Assistant), computer or any other type in wireless environment.
As described below, term " evolved Node B " include but are not limited to base station, site controller, access point (AP) or any other type can be in wireless environment interface operable equipment.
Fig. 1 shows the wireless communication system 100 that comprises WTRU 105 and eNB 110, and wherein WTRU105 and eNB 100 communicate by physical downlink control channel (PDCCH) 115 and physical uplink control channel (PUCCH) 120.Described WTRU 105 comprises transmitter 125, receiver 130, processor 135 and buffer 140.Described eNB 110 comprises transmitter 145, receiver 150 and processor 155.
Indication to the release of DL persistent resources is sent by the transmitter among the eNB 110 145, and is received by the receiver among the WTRU 105 130 via PDCCH 115.Transmitter 125 among the WTRU 105 sends ACK to eNB 110, and this ACK shows that described indication is received.Buffer 140 is used to store DL distribution and DL transmission data.ENB 110 can use PDCCH or MAC CE to come by the described indication of signalisation.At least one bit can be added on the content of the PDCCH that will pass through signalisation, is used for the distribution of DL persistent resources or is used for the DL Dynamic Resource Allocation for Multimedia to signal PDCCH.Described DL persistent resources is released subsequently, and sends the d/d indication of DL persistent resources by the transmitter among the WTRU 105 125.
Explicit DL persistent resources discharges
Disclose and a kind ofly be used to use explicit signaling to come method by the release of signalisation DL persistent resources.When explicit signaling is used to from eNB 110 during to release by signalisation DL persistent resources of WTRU 105, as shown in Figure 1, PDCCH or MAC CE can be used to the release by the described DL persistent resources of signalisation.
If PDCCH 115 is used to explicit signaling, then at least one bit can be added on the PDCCH115, is used for the distribution of DL persistent resources or is used for the DL Dynamic Resource Allocation for Multimedia to signal PDCCH 115.A bit that adds PDCCH 115 to also can be signaled WTRU 105 and use independent cell-radio network temporary identifier (C-RNTI), or uses the reserved value of some other fields, such as through-put power control (TPC) field.
Subsequently, WTRU 105 sends ACK/NACK to confirm to receive the PDCCH release signaling to eNB 110.Replacedly, after WTRU 105 discharged described DL persistent resources, WTRU 105 sent indication to confirm the successful release of DL persistent resources to eNB 110.About the release of UL persistent resources, eNB 110 confirms implicitly that by the losing of resource that detects previous distribution described resource discharges.
Be not used for the release that lasting field of distributing can be used to indicate DL or UL persistent resources on the PDCCH.For example, can use two bits in the TPC field, the wherein release of " 00 " indication DL persistent resources, and two bits " 01 " in the TPC field can be used to indicate the release of UL persistent resources.
Can use special MAC CE to come release by signalisation DL and UL persistent resources.For example, two bits " 00 " among the MAC CE can be indicated the explicit release of DL persistent resources, and two bits " 01 " can be indicated the explicit release of UL persistent resources.Bit number among the MAC CE can change, and can discharge the different array of predefine with the UL persistent resources for DL.
If WTRU 105 does not successfully receive PDCCH or blind Detecting and do not indicate any new DL packets of voice M time in pre-configured TTI, then WTRU 105 can discharge described DL persistent resources.TTI is used for continuing to receive.This method can WTRU implicit expression resource be released to feature.Whether still can receive the DL dynamic service according to WTRU 105, WTRU 105 should follow the principles, to enter long or short discontinuous reception (DRX) circulation (cycle).After having discharged the DL persistent resources, WTRU 105 also can select whether to send indication to eNB 110, with the autonomous release notice eNB110 with the DL persistent resources.Can use next available period PUCCH or send described indication by new UL MAC CE.
Replacedly, when WTRU 105 during WTRU 105 enters talkburst (talk-spurt) after the state when eNB 110 receives a DL system banner number (SID), because state was finished during WTRU 105 determined talkburst, WTRU 105 will discharge the DL persistent resources.WTRU 105 can optionally send indication to eNB 110 subsequently, with the release of indication DL persistent resources.
Implicit expression DL persistent resources discharges
Disclose and a kind ofly be used to use conceal signaling to come method by the release of signalisation DL persistent resources.WTRU handles similar to the rule of the implicit expression release of DL persistent resources with the failure when explicit DL persistent resources signal is not received.Yet, be used for handling the WTRU rule that implicit expression DL persistent resources discharges and still have difference.
Receive PDCCH 115 if WTRU 105 fails, and/or blind Detecting fails in pre-configured TTI any new DL packets of voice of indication M time, then WTRU 105 can discharge described DL persistent resources.Whether still can receive the DL/UL dynamic service according to WTRU 105, WTRU 105 should follow the principles, to enter long or short DRX circulation.When WTRU 105 circulates to short DRX from long DRX varying cyclically, or from lacking the DRX varying cyclically to long DRX circulation time, WTRU 105 will report described change to eNB 110 in (on-duration) (or activationary time) during the opening of new DRX circulation, thereby eNB 110 is known the change of WTRU DRX circulation, and transmission DL signaling in avoiding during the opening of the circulation of mistake.
After the DL persistent resources was discharged by implicit expression, WTRU 105 can be optionally sends the indication of the autonomous release that is used to indicate the DL persistent resources to eNB 110.The release of DL persistent resources is confirmed in this indication.This indication can be used next available period PUCCH or send by new UL MAC CE.
Replacedly, after WTRU 105 is during the talkburst of WTRU 105 when eNB 110 receives a DL SID, because state was finished during WTRU 105 determined talkburst, WTRU105 will discharge the DL persistent resources and go forward side by side into mourning in silence (silent) cycle.WTRU 105 can optionally send indication to eNB 110 subsequently, is used to indicate the release of DL persistent resources.This indication can be used next available period PUCCH or send by new UL MAC CE.
Explicit UL persistent resources discharges
Disclose and a kind ofly be used to use explicit signaling to come method by the release of signalisation UL persistent resources.
Buffer state reports (BSR) afterwards to send empty (empty) buffer (or filling) at WTRU 105 to eNB 110, use the indication of PDCCH from the explicit release of eNB transmission UL persistent resources, wherein said empty buffer device (or filling) BSR is used for indication does not have the UL data to be sent to eNB 110 by WTRU105.The transmission of the indication that explicit UL persistent resources discharges can be generated repeatedly, to reduce the non-successful possibility that receives at WTRU 105 places.WTRU 105 can optionally use ACK/NACK that feedback is provided.The transmission of the indication that described explicit UL persistent resources discharges can be carried and be finished on other MAC PDU or carry out multiplexing with other MAC PDU.The indication that explicit UL persistent resources discharges can be used next available PDCCH or send by new DL MAC CE.
After WTRU 105 successfully received the UL persistent resources, WTRU 105 can be subsequently be sent to eNB 110 with the indication that is used to confirm the release of UL persistent resources.
Replacedly, if eNB 110 fails to detect the follow-up UL transmission about the UL persistent resources, then the affirmation of the release of UL persistent resources is implicitly finished.
When explicit UL persistent resources release signal by when eNB 110 is sent to WTRU 105, may exist indication to lose or wrong failure conditions.Following method is disclosed so that failure conditions is handled.
If eNB 110 does not receive NACK from WTRU 105 after transmitting the explicit release signal of UL persistent resources, then eNB 110 transmits the explicit release signal of UL persistent resources once more, until reaching maximum retransmission.WTRU 105 should from eNB 110 receive the explicit release signal of UL persistent resources the subframe of expection, after WTRU 105 transmits empty BSR, if WTRU 105 does not receive any feedback from eNB110, then do not have in buffer after N TTI under the situation of any new UL VoIP grouping, WTRU 105 independently discharges the UL persistent resources.
Replacedly, if WTRU 105 does not receive any feedback from eNB 110 after transmitting empty BSR, then WTRU 105 discharges the UL persistent resources immediately.
Replacedly, if WTRU 105 transmits empty BSR and do not receive the explicit release signal of UL persistent resources from eNB 110, then WTRU 105 did not discharge the UL persistent resources before having effective UL SID.Afterwards, WTRU 105 send be used for the SID transmission dispatch request (SR) to eNB 110 so that eNB 110 determine WTRU 105 from talkburst duration state exchange to silence period.Thus, WTRU 105 has independently discharged the UL persistent resources.
Replacedly, after WTRU 105 discharges the UL persistent resources and enters into new DRX circulation, (depending on DL/UL dynamic service amount), WTRU 105 transmits UL and is indicated to eNB 110, and wherein this indication has represented that the beginning of the release of UL persistent resources and DRX circulation newly is so that WTRU 105 is synchronous with eNB 110.Can in next PUCCH, use physics (PHY) signaling to transmit described UL indication.Replacedly, described UL indication is controlled (RRC) signaling as new MAC CE or radio resource in the line link shared channel (PUSCH) physically.New MAC CE is used to indicate the implicit expression of the UL persistent resources of being undertaken by WTRU 105 to discharge.
Implicit expression UL persistent resources discharges
A kind of method of using conceal signaling to signal the release of UL persistent resources is disclosed.
WTRU 105 detect no longer include the UL voice data packet after, WTRU 105 transmits PHY indication among empty buffer device (or filling) BSR, the PUCCH or MAC CE to eNB 110, changes with indicating status also implicitly to discharge the UL persistent resources immediately.WTRU 105 transmits empty buffer device (or filling) BSR on N continuous semi-continuous subframe.
Replace in the execution mode at one, WTRU 105 only transmits empty (or filling) BSR once and wait for and reach N-1 continuous semi-continuous subframe whether to have new speech data effective in definite buffer.If there is not new speech data in the buffer during this period, then WTRU 105 discharges the UL persistent resources.
Replacedly, when WTRU 105 has ULSID when grouping that will transmit from entering the talkburst state, WTRU 105 discharges the UL persistent resources.WTRU 105 can have SID when grouping in buffer, WTRU 105 sends after the SR or WTRU 105 discharges the UL persistent resources after transmitting UL SID grouping.
Replacedly, after WTRU 105 discharges the UL persistent resources and enters new DRX circulation, (depending on DL/UL dynamic service amount), WTRU 105 transmits UL and is indicated to eNB 110, wherein, this indication has represented that the beginning of the release of UL persistent resources and DRX circulation newly is so that WTRU 105 is synchronous with eNB 110.Can in next PUCCH, use the PHY signaling to transmit described UL indication.Replacedly, described UL indication can be as new MAC CE or radio resource control (RRC) signaling in PUSCH.New MAC CE is used to indicate the implicit expression of the UL persistent resources of being undertaken by WTRU 105 to discharge.
The activation of persistent resources and reconfigure signaling
Disclose a kind of conceal signaling that uses and signaled the activation of persistent resources and the method that reconfigures.New field is added into the start-up time that PDCCH 115 distributes with indication DL or UL persistent resources.Described new field can be the form of start-up system frame number (SFN).Replacedly, be used for continuing the PDCCH 105 of distribution when WTRU 105 has successfully decoded, DL or UL persistent resources are distributed and can be triggered under the situation of not using start-up time.After the PDCCH 115 that successfully decoding is used for continuing to distribute, DL or UL persistent resources are distributed in next subframe or N subframe place triggered immediately.
In order to reconfigure UL and DL persistent resources, except using the RRC signaling, can use PDCCH 115 or MAC CE.When using PDCCH 115 and/or MAC CE to reconfigure persistent resources, can use following steps to reconfigure UL or DL persistent resources.
1) if only need reconfigure radio resource and transformat, then PDCCH 115 is used in and comprises new resource and transformat (TF) information under the situation that changes PDCCH 115 contents indistinctively.
2) if the informational needs such as periodicity and/or at least one new HARQ process disposes with described resource and transformat, then PDCCH 115 and MAC CE all can be used for reconfiguring new resource and TF.
